Study summary

This study is an observational study on the efficacy and safety of auto-HSCT in adult patients with Burkitt lymphoma, lymphoblastic lymphoma, and acute lymphoblastic leukemia who received TCCA conditioning regimen. The study plans to include 28 patients who received the TCCA regimen for pre-transplantation pretreatment before auto-HSCT. Maintenance treatment will be carried out after transplantation for 1 year to observe the efficacy and safety.

Inclusion criteria

    1. Voluntarily sign the form, which must be signed by the patient himself.

      1. ALL patients confirmed by bone marrow cell morphology, immunology, and genetics; 3. PH+ALL patients who achieve s3CMR (definition: achieve molecular biological remission in the early stage of initial treatment (within 3 months) and maintain remission); 4. Ph-B-ALL patients who have reached MRD- after 3 courses of chemotherapy and continue to be MRD-; adult patients with Burkitt lymphoma and lymphoblastic lymphoma confirmed by histopathology and molecular genetics; 5. Adult patients with Burkitt lymphoma and lymphoblastoma, if the bone marrow is not involved, can achieve PR or above after induction; if the bone marrow is involved at the time of initial diagnosis, 3 courses of chemotherapy are required to reach MRD- and continue to be MRD-.
      1. Patients receiving hematopoietic stem cell transplantation (auto-HSCT); 7. Age ≥18 years and ≤65 years old, male or female; 8. Performance Status (ECOG-PS) score of 0-2;

      2. Myocardial infarction less than 6 months from study enrollment;
      3. Have a history of arrhythmia that requires drug treatment or has severe clinical symptoms;
      4. Uncontrolled or symptomatic congestive heart failure (> class 2);
      5. The is lower than the lower limit of the normal range. 7. Patients who meet the following criteria:

      <!-- -->

      1. Major surgery (except diagnostic surgery) is planned within 4 weeks before enrollment or during the study period, or the surgical wound has not fully healed before enrollment;
      2. Those who have received (attenuated) within 4 weeks before enrollment;
      3. Patients with suspected active or latent tuberculosis;
      4. Participate in other clinical trials one month before enrollment 8. Those who the researcher believes are not suitable for enrollment
Terms in these criteria, in plain language(10)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Allogeneic and autologous transplant

Stem cell (bone marrow) transplants. Allogeneic uses cells from a donor; autologous uses your own cells, collected earlier and given back.

ECOG performance status

A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.

0
Fully active, no restrictions.
1
Limited in strenuous activity, but walking and able to do light work, such as housework or office work.
2
Walking and able to look after yourself, but unable to work; up and about more than half of waking hours.
3
Able to look after yourself only in part; in bed or a chair more than half of waking hours.
4
Unable to look after yourself at all; in bed or a chair all day.

Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Hepatitis B tests

Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.

Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.

Hepatitis C tests

Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.

After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

NYHA class (heart failure)

The New York Heart Association’s four classes of how much heart failure limits physical activity.

I
No limits: ordinary activity causes no undue tiredness or breathlessness.
II
Slight limits: comfortable at rest, ordinary activity causes symptoms.
III
Marked limits: comfortable at rest, less than ordinary activity causes symptoms.
IV
Symptoms even at rest; any activity makes them worse.

Studies set their own limit — many outside heart failure leave out class III–IV, while heart failure studies may ask for a particular class. Check the class this study names.

LVEF (left ventricular ejection fraction)

The share of blood the heart’s main pumping chamber (the left ventricle) pushes out with each beat, measured by an echocardiogram (heart ultrasound) or a MUGA scan. About 50–70% is normal.

Live vaccines

Vaccines made with a weakened form of the germ, such as measles–mumps–rubella (MMR), chickenpox and yellow fever. They can be risky when the immune system is weakened. Flu injections are not live; the nasal flu spray is.
